1. Safety instructions • NEVER fire a flash in the immediate vicinity of the eyes! Flash fired directly in front of the eyes of a person or animal can damage the retina and lead to severe visual disorders - even blindness! • Spent batteries should be immediately remo - ved.
5 2. Preparing the mecablitz for use 2.1 Power supply The flashgun can only be operated with 2 CR2- type lithium batteries. This type of battery can be stored for many years with practically no loss of energy, thus making it ideal for occasional amateur flash photography.
2. Preparing the mecablitz for use 6 When loading the batteries ensure correct polarity. Incorrectly loaded batteries can dest- roy the flashgun! All batteries must be of the same make and have the same charge level.
7 3. Setting the mecablitz into operation 3.1 Preconditions The mecablitz must only be used with TTL flash controlled cameras! The sensor of TTL flash controlled cameras measures the light reaching the film through the camera lens and instantly cuts out the flash when the film has been correctly expo- sed.
4. Flashgun instructions to the camera The mecablitz transmits different signals and messages to the camera when it is connected to the camera and is switched on. 4.1 Flash-ready indication The green light on the mecablitz illuminates when the flash capacitor is fully primed, thereby indicating flash readiness.
4. Flashgun instructions to the camera 4.4 Information displayed in the camera’s viewer The following table only gives a general survey. Camera-specific deviations ar possible (please refer to the camera’s operating instructions. • Green arrow Indicates that flash- gun should be used or switched on.
5. TTL flash control The mecablitz receives its information exclusi- vely from the connected TTL-controlled camera. Exposure measurement in TTL mode (TTL = t hrough- t he- l ens) is completed by the camera’s sensor. This sensor measures the light reaching the film through the camera lens.
6. Flash synchronisation Different modes of flash synchronisation are pos- sible, depending on the camera model. Please refer to the camera’s operating instructions to find out how the individual modes of synchronisation are set on the camera.
6. Flash synchronisation 6.3 Second curtain synchronisation (REAR) Some cameras offer the facility of second shutter curtain synchronisation. With normal synchronisation, the flash is fired precisely after the opening of the first shutter curtain.
7. Flash in the individual camera modes Use of flash in the program modes TTL-controlled flash shots can be made in all exposure and auto program modes. Once the mecablitz is attached to the camera and switched on, it automatically operates with TTL flash control in auto program (P), aperture priority (A), shutter priority (S) and manual (M) modes.
8. Autofocus measuring flash The integrated AF red-light beam of the mecablitz supports the automatic focusing of autofocus TTL cameras. When the prevailing light is insufficient for automatic focusing, the mecablitz will project a pattern of red vertical stripes onto the subject as soon as the camera’s release is lightly touched.
8. Autofocus measuring flash AF operating modes Two operating modes are available with AF came- ras (depending on the camera model): • Focusing priority (SINGLE AF): The shutter can only be released when the subject has been sharply focused by the AF system.
9. Flash techniques and flash functions 9.1 Automatic fill-in flash Some cameras offer the facility of activating auto- matic fill-in flash control or automatically trigger a fill-in flash. Fill-in flash will soften harsh shadows and diminish the contrast, thereby producing a more balanced exposure when shooting against the light.
10. Lighting and attachments Your mecablitz provides full and even illumination of normal 24 x 36 mm negatives when using len- ses of 35 mm focal length and longer. A wide-angle diffuser is supplied with the flash- gun to increase the coverage if you wish to use a 28 mm wide-angle lens.
18 11. Care and maintenance - T roubleshooting Remove grime and dust with a soft, dry cloth. Do not use cleaning agents as these could damage the plastic parts. Forming the flash capacitor The flash capacitor incorporated in the flashgun undergoes a physical change when the flashgun is not switched on for prolonged periods.
